Abstract
Knockdown furniture comprising flat, interlocking, planar parts assembled or disassembled without tools or fasteners. A flat top is supported above ground. A plurality of identical, generally C-shaped legs operatively oriented in radially, spaced apart relation upon erection, support and elevate the top. Each leg comprises a foot touching the ground, an arm for grasping the top, and a wedging section of varying width that is oriented generally perpendicularly. A planar lock shaped like and parallel with the top engages the leg wedging regions. The legs penetrate slots defined in the lock and are thus captivated. Each leg intermediate section may vary in width, with the outside of each intermediate leg section comprising a ramp, and the inside forming a complementary leg edge. The wedging action resulting from slot-to-ramp engagement locks the parts together, with the complimentary leg edges firmly abutting one another.
Description




BACKGROUND OF THE INVENTION




I. Field of the Invention




The present invention relates generally to modular furniture items. More particularly, my invention relates to portable, knockdown furniture items comprising a plurality of flat, readily transportable parts that can be easily erected or disassembled without special tools.




II. Description of the Prior Art




The prior art recognizes that modular, knockdown furniture items have a variety of useful applications. One advantage of modular construction is that the device parts may be shipped in a flat configuration in disassembled form. The user can then simply fit the parts together to create a piece of furniture. With a variety of parts of different shapes and sizes, the user can create different artistic effects as well as different furniture forms. Once at the application site, the parts should fit together reliably and easily to facilitate erection.




Furniture articles that can be folded or disassembled into individual, flat constituent parts can more easily be stored and transported. When unassembled and piled together, flat parts will occupy a minimum amount of storage space. Hunters, campers, and other outdoor users, for example, prefer knockdown items, as they can easily be stored, hauled to the camp site, and erected for use in a shot period of time. The user can easily put the items together, as long as simplicity of design is maintained, and especially where the design omits irregular or complex parts. Favorable designs should comprise parts that may be quickly and easily assembled without the use of hand tools. The requirement of special tools is especially disadvantageous. Furniture items comprising a minimum of parts that fit together reliably without the necessity to read or study manuals or other documentation are preferred.




One problem with modular furniture is that sturdy, assembled structures are difficult to erect with parts that are easily assembled and disassembled. Some prior art knockdown articles have recognizable disadvantages. Some devices comprise too many parts, and sometimes tools or special fasteners are required for erection. Some knockdown devices comprise intricate parts that are too expensive. Some folding furniture devices require assembly by relatively skilled personnel. Some knockdown articles cannot withstand heavy use, and they will not reliably support heavy loads. Known devices that do not require fasteners and/or hand tools for assembly or disassembly lack the mechanical durability and dependability required for commercial success.




The most reliable and durable prior art knockdown furniture items have all required tools or multiple fasteners. An easily assembled knockdown arrangement that consists only of flat pieces, and which can be hand-assembled into a durable and powerful furniture article would be highly desirable.




SUMMARY OF THE INVENTION




All embodiments of my knockdown furniture comprise a plurality of flat, planar parts that can be easily erected without hand tools or fasteners. The assembled items are easily disassembled, and the light-weight, flat parts can be quickly separated and stored for transportation.




Each furniture item comprises a plurality of identical, generally C-shaped legs, a relatively large, flat top supported by the legs, and a planar lock in the form of an intermediate surface disposed by the legs below the top. The top may be circular, or it may be in the form of a regular polygon. The lock may be shaped similarly, but preferably it is smaller than the top. Each leg is generally C-shaped, comprising a foot for touching the ground or floor, an upper arm for grasping the top, and an intermediate section that is oriented generally perpendicularly relative to ground when assembly is completed.




Special slots are defined in the lock for receiving the legs, which are first rotated during assembly until the legs are vertical, with their midsections confined and captivated within the lock slots. Importantly, each leg intermediate section varies in width. The outside of the leg intermediate region comprises a ramp. The inside of the same area forms a complementary leg edge. The distance between the ramps structure and the complimentary edges varies, to enable a wedging action in response to the lock. The legs assume a position in assembly wherein they are radially spaced apart, with the inner, complementary leg edges of each leg midsection abutting one another. At the same time, the leg's ramps contact the outermost ends of the lock slots, in which the legs are inserted and confined. Once the legs are installed, the lock can be pressed downwardly to firmly, compressively secure the legs and the rest of the parts together. The leg arms have hooks that firmly grasp the top in assembly.




This invention provides a knock down furniture design comprising a plurality of flat, planar parts that can be fitted together without tools or fasteners. Once assembled the device functions durably and dependably until dissembled as desired.




Thus a basic object of my invention is to provide a knockdown furniture item comprised only of flat, interfitting parts that can assembled without tools or fasteners.




Another basic object is to provide a robust furniture item that can be easily stored and transported.




A fundamental object is to provide a furniture item of the character described that can be user-erected without tools.




Similarly, it is a broad object of my invention to provide a knockdown furniture item comprising a minimal number of parts.




Yet another important object is to provide a furniture item of the character described that can be deployed in the form of a table, chair or other desired furniture article.




Another object is to provide a stool, table or similar furniture article that can be stored in a completely flat orientation.




A similar object is to minimize stowage and transportation volume requirements.




Another important object is to provide a similar furniture article of the character described which is lightweight and sturdy.




A still further object is to provide a modular knockdown furniture item such as a table or chair whose components can be sold in kit form easy assembly.




Yet another broad object is to provide an article of furniture comprising generally planar parts that are made of sheet or board material.




Another important object is to enable the user to quickly erect a durable and sturdy furniture article without special training.




A similar object is to enable the user to quickly erect a sturdy and durable furniture item without the need for referencing complex manuals or instructions.




A fundamental object is to provide a modular, knockdown furniture construction of the character described comprised of parts that may be manufactured from plastic, corrugated material, cardboard, plywood or the like.




These and other objects and advantages of the present invention, along with features of novelty appurtenant thereto, will appear or become apparent in the course of the following descriptive sections.

DETAILED DESCRIPTION




Turning initially now

FIGS. 1-12

to the drawings, a preferred embodiment of my knockdown furniture invention comprises a table, generally designated by the reference numeral


30


. Table


30


comprises a plurality of planar parts to be described later, that can all be made from planar material such as cardboard, fiber board, corrugated, plywood or the like. The parts may be assembled or disassembled, as described later, without hand tools, and when assembled, a rigid and dependable furniture item is created. No special fasteners are required.




Table


30


comprises the three main components laid out for convenient viewing in FIG.


9


. These are legs, generally designated by the reference numeral


32


, a planar, generally polygonal top, broadly designated by the reference numeral


34


, and an intermediate, planar lock, generally designated by the reference numeral


36


. When the foregoing parts are assembled, as described in further detail hereinafter, the legs are inserted through the slot structure


39


(

FIG. 4

) defined in the lock


36


, and they reach upwardly and engage and support top


34


. Once they are inserted and properly juxtapositioned by the assembler, the lock


36


is pressed downwardly to secure the legs in radially spaced-apart orientation, firmly grasping the top and reinforcing the leg structure. As hereinafter further described, the furniture item (i.e., table


30


) results. It is adapted to be deployed upon a firm, planar, supporting surface such as floor


37


(FIG.


1


). When assembled, the table legs


32


are firmly pressed against one another in an edgewise fashion, with the table top


34


is disposed vertically above the lock


36


. When properly deployed, lock


36


will be parallel with top


34


. The exposed, upper supporting surface


35


of table top


34


presents a strong and durable support for a variety of items, including picnic supplies, silverware, plates, pots and pans and the like.




In table embodiment


30


the top


34


is preferably octagonal, comprising eight symmetrical edges


40


(

FIG. 2

) that are radially spaced apart about the center of table surface


35


. This configuration is but one of many that may be adopted. For example, the top


34


may be round, triangular, hexagonal, or square. It may assume the shape of any regular polygon. Where legs of varying configurations are allowed, then the top may assume a rectangular shape, or even irregular shapes, resembling trapezoids, truncated cones, semicircles and/or the like. Preferably the legs form a symmetrically array, placed radially about the structure. Preferably there are a number of legs


32


at least equal to three, and preferably equal to an integer fraction of the number of top sides. For example, where an octagonal top


34


is chosen, eight table sides result, and eight divided by the integer two yields four legs. As will become apparent hereinafter, the number of legs could equal the number of table top sides, particularly with a square top. Preferably the design contemplates one leg


32


for each two table top sides.




The preferred legs


32


are all planar, and preferably, in a typical package of components sold as a kit for example, each leg is identical. With primary reference directed to

FIGS. 4

,


5


and


9


,


10


, the legs comprise a bottom foot


46


, an upper arm


50


, and an integral midsection


48


. Each foot


46


comprises a terminal bottom edge


49


(

FIG. 5

) adapted to be disposed upon a supporting surface


37


(

FIG. 1

) when the assembly is constructed. Foot


46


upwardly transitions to midsection


48


(FIG.


4


). The outer edge


51


(

FIG. 4

) of each foot meets the supporting ledge


52


(

FIGS. 4

,


5


) formed on the outside of midsection


48


. A step-like, stair-shaped wedging region


53


is formed on the outside of the legs, spaced apart from the specially configured, complimentary inner edges


54


(

FIG. 9

) of each midsection


48


. Importantly, the width of the leg across the intermediate portions


48


varies. In other words the distance between the inner edge


54


and the opposite, outer wedging region


53


preferably increases as one moves downwardly. As explained later, this facilitates a locking action as the lock is pressed into position.




Each arm


50


integrally extends angularly upwardly and outwardly from midsection


48


(i.e., FIG.


10


). The inner, upper arm edges


58


and


59


, and upper, supporting ledge


60


(

FIG. 8

) transition away from special edge


54


of the midsection


48


. The lower, outer edge


61


of the arms is substantially straight. As best seen in

FIG. 5

, the midsection's wedging region


53


comprises an angled edge


62


(

FIG. 5

) that adjoins arm upper edge


61


, and raised, projecting region


53


(FIG.


5


). Region


53


comprises a first ramp


67


(

FIG. 8

) and a second ramp


69


(FIG.


5


). Ramp


67


adjoins angled midsection edge


62


. Ramp


69


adjoins ramp


67


and ledge


52


(FIG.


5


). Region


53


effectively causes the width across the leg midsection to vary; i.e., the width between edges


54


and


62


is less than the width between edge


54


and ramps


67


or


69


. The lock wedges the parts together as it is pressed downwardly, with the leg midsection captivated within the lock slots described later. In other words, in assembly, with the legs juxtapositioned between the orientations of

FIGS. 5 and 10

.

FIG. 5

shows the lock partly installed upon the loose legs, and

FIG. 10

shows the firm, leg alignment maintained by the lock after it has been pressed into place.




The upper arm


50


of each leg


32


terminates in a generally C-shaped hook


70


(

FIGS. 5

,


8


,


10


) that projects from exposed ledge


60


of the arm. When assembled, the arm ledge


60


will support the table top


34


previously described, as the various table edges


40


can be fitted within channels


72


so the arms support the table top. The upper ledges


60


of the each leg are parallel with ledges


52


(

FIG. 4

) that support the lock


36


. Hook


70


comprises an inwardly projecting channel


72


that receives edges of the table top upon assembly. The channel


72


results from the generally C-shaped terminus


73


at the top of each leg's upper arms


50


. Channels


72


(

FIG. 8

) will be arranged symmetrically, in a radially spaced apart configuration conforming to the placement of the legs upon assembly. Upon proper assembly, the exposed upper surface


74


(

FIGS. 8

,


10


,


11


) of each terminus will be oriented parallel with ledges


52


and


60


previously described, with adjoining vertical surface


75


(

FIG. 10

) oriented perpendicularly.




The lock


36


is best addressed with concurrent reference to

FIGS. 4

,


9


,


11


, and


12


. It will be observed that the generally planar lock is flat and square. It's shape is not as important as the fact that it contains an internal, central slot structure


39


, which is symmetrical. With four legs, it is preferably in the form of a cross, with one individual slot to receive each leg. In this embodiment, four individual radially spaced apart slots


80


(

FIG. 4

) are defined in the lock


36


. The lock


36


has a plurality of symmetrical sides


81


(

FIG. 9

) forming, in this instance, a square shape. The shape can be different, as apparent to those with skill in the art. The number of slots preferably equals the number of legs to be used. In the best mode of this embodiment, the four, individual radially spaced-apart slots


80


meet at the center


82


of the lock, and the outermost slot ends project towards the lock corners. The slots are dimensioned carefully to frictionally and firmly receive and lock the legs. The distance from a slot end


83


to the slot center


82


(

FIG. 9

) roughly approximates the width of the leg midsection or wedging region as measured between inner edge


54


(i.e.,

FIGS. 4

,


5


,


9


) and the ramps


67


,


69


(

FIGS. 5

,


10


).




Proper dimensioning of the legs and the lock slots is important. As best seen in

FIGS. 11

,


12


, the leg midsection inner edges


54


are preferably stepped, comprising a notch


90


and a projection


91


. When the legs are compressed together in the assembled shape, the notch of one leg abuts the notch of the others, forming the arrangement of FIG.


12


. However, the inner edges of the legs could be designed differently. For example each could be shaped like a pointed arrow. Importantly, the critical fitting distance between one leg projection


91


(

FIG. 12

) and the outer end


83


of a corresponding slot has been designated by reference numeral


85


(FIG.


12


). This distance


85


is preferably equal to the width between inner edge


54


and ramp


69


.




The legs are thus bound together in frictional, compressive abutting relation as in

FIG. 12

, by compressive action of the lock


36


as it is pressed down over the legs during assembly. The variable width midsection region (i.e., the leg width between ramps


67


, and edge


54


) is captivated within lock slots of finite length; as the lock is pressed downwardly, with the legs properly oriented, action of the ramps


67


,


69


sliding against the outermost limits of the lock slots results in compression. The legs are compressed slightly, as they are firmly drawn together by the lock. At the same time, the inner edges


54


of each leg mutually abut one another (FIG.


12


). The various projections


91


(

FIG. 12

) abut in the mutually facing notches


90


to form a stable, radially interlocking structure. The compressed legs will remain stable in this radially interlocking arrangement, with predetermined compressive forces from the properly mounted lock


36


maintaining all the parts together.




Assembly:




Referring to

FIG. 9

, the flat pieces should be recognized, and laid out in a flat, symmetrical arrangement prior to assembly. A prudent assembler will be cognizant of the preferred, target configuration seen in FIG.


1


. As seen in

FIG. 6

, the arms


50


of each leg are first thrust into the various slots


80


of the planar lock


36


, and preferably, their generally radially spaced-apart target orientation is preserved. As the legs reach upwardly and are positioned vertically, their hooks


70


may engage the table top


34


. As the pertinent table top edges


40


are firmly received within the channels


72


(

FIG. 10

) alignment begins. The width of the leg's midsection between wedging region


53


(i.e., ramp edge


67


,


69


) and inner edge


54


increases from top to bottom. The legs may first be arranged in a generally radially spaced apart, vertical orientation as in FIG.


4


. Then the lock


36


is “installed.” Essentially, the legs are first thrust within the lock slots


80


and then rotated about their midsections to transform them between the orientations depicted in

FIGS. 5 and 10

. Once the legs are rotated to assume the desired orientation wherein they grasp top


34


, the lock


36


may be gently pressed downwardly, until resting upon ledges


52


(

FIG. 5

) and forming the stable assembly. This locks “wedges” the parts into position with its slot ends


83


(

FIG. 9

) being wedged against the ramping surfaces


69


(

FIG. 5

) defined in the leg midsections. Once the lock


36


is pressed downwardly until it firmly rests upon the previously described leg ledges


52


(FIG.


4


), assembly is completed, and the arrangement will remain stable and fixed.




First Alternative Embodiment:




An alternative embodiment (i.e., the second embodiment) seen in

FIGS. 13-21

of the drawings comprises a chair


130


. Alternatively it can be used as a stool, or a table or a shelf. Chair


130


comprises a plurality of legs


132


, a preferably circular top


134


, and a preferably circular lock


136


. In this embodiment, the lock is sized and configured somewhat like the top


134


. As before, when the aforementioned planar parts are correctly assembled, a strong and dependable structure results.




Each leg


132


(

FIG. 20

) is identical. With primary reference directed to

FIGS. 16

,


20


and


21


, the legs comprise a bottom foot


146


, an upper arm


150


, and an integral midsection


148


. As before, a step-like, stair-shaped wedging region


153


(

FIG. 21

) is formed in the midsection at the angular vertice formed by foot


146


and arm


150


. Each arm


150


integrally extends angularly upwardly and outwardly from each corresponding midsection


148


. An upper supporting ledge


160


supports the top


134


after assembly. The lower ledge


154


supports the lock


136


in the same manner as that previously described.




As best seen in

FIG. 21

, the leg midsection's all comprise a wedging region


153


having a pair of angled ramp portions that function as described previously when the legs are compressed within the locks slot structure


139


As before, each leg


132


terminates at its top in a generally C-shaped hook


170


that captivates the top


134


upon assembly. The lock's slot structure


139


, is symmetrical, in the form of a cross, and comprises four individual radially spaced apart slots


180


(

FIG. 21

) to fit the four legs. These slots are dimensioned carefully to frictionally and firmly receive and lock the legs as previously described. Assembly occurs as previously described.




Second Alternative Embodiment:




A third embodiment seen in

FIGS. 22-26

of the drawings comprises a table


200


which can also be used as a stool or shelf. Table


200


comprises a plurality of similar, flat legs


202


, a preferably circular top


204


, and a preferably circular lock


206


that has a smaller diameter than table top


204


. Of course top


204


and lock


206


can be shaped or dimensioned differently, as will be appreciated by those skilled in the art. In this embodiment, the lock is also sized and configured somewhat like the top


204


. Once again, when the aforementioned planar parts are correctly assembled, a strong and dependable structure results. However, the lock


206


is coupled to the legs through a different arrangement. While the indicated structure is slightly different, principles of operation remain largely the same.




Each identical leg


202


comprises a bottom foot


208


, an integral upper arm


210


, and an integral locking protrusion


212


. As with the prior embodiments, each leg


202


terminates at its top in a generally C-shaped hook


221


(

FIG. 26

) that captivates the top


204


upon assembly. Unlike prior embodiments, lock


206


is not penetrated by the arms of the legs, rather, it is fitted to the abutting protrusions


212


. Each protrusion


212


defines a step-like, stair-shaped wedging region


215


that tightly fits through slot structure


218


defined in lock


206


. Each arm


210


integrally extends angularly upwardly and outwardly from the corresponding protrusion


212


. An upper supporting ledge


220


on each arm


210


jointly supports the table top


204


after assembly. The lower ledge


230


supports the lock


206


in the same manner as that previously described.




As best seen in

FIG. 26

, the wedging region


215


comprises a straight, perpendicularly upwardly extending edge


222


defined on protrusion


212


that is spaced apart from and parallel with the legs elongated inner edge


225


. Inner edge


222


adjoins the upwardly extending, inclined protrusion edge


224


that functions as a ramp. Edge


224


extends upwardly to flat, protrusion top


226


. The spaced-apart arm


210


has an inclined upper edge


228


that extends angularly upwardly from the arm's lower vertical edge portion


229


(FIG.


26


). Arm vertical edge portion


229


is spaced apart from and parallel with protrusion edge


222


, with a flat, lower ledge


230


defined therebetween.




The lock's slot structure


218


(

FIG. 22

) is symmetrical, preferably in the form of a cross, for embodiments using four legs. There are four individual, radially spaced apart slots


234


(

FIG. 22

) to fit the four legs. These slots are dimensioned carefully to frictionally and firmly receive and lock the legs as previously described. They are dimensioned substantially the same as dimension


231


in

FIG. 26

so that firm locking engagement occurs when the lock is press fitted downwardly over the abutting protrusions on the radially-aligned leg structures. When pressed downwardly, the slot structure edges


224


first penetrate slot structure


218


, and as pressure continues, the lock is frictionally snap-fitted in firm compressive engagement between aligned, coplanar legs whose protrusions occupy the lock slots. The lock comes to rest upon lower ledge


230


. Additionally, each lock comprises radially spaced apart, peripheral notches


240


that are aligned with individual slots


234


(FIG.


22


). In assembly, the lock notches


240


firmly receive and abut arm edges


229


(

FIG. 26

) previously described, to create further frictional locking forces upon assembly.




From the foregoing, it will be seen that this invention is one well adapted to obtain all the ends and objects herein set forth, together with other advantages which are inherent to the structure.




It will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations. This is contemplated by and is within the scope of the claims.




As many possible embodiments may be made of the invention without departing from the scope thereof, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.

  • 3. A modular, knockdown furniture item adapted to be disposed upon a generally flat or horizontal supporting surface, the furniture comprising:a generally planar top adapted to be supported vertically above said surface; a plurality of generally C-shaped, planar, radially spaced apart legs, each leg comprising a lower foot for contacting said supporting surface, an integral upper arm for grasping said top, and an integral midsection of nonuniform width between said foot and said top; a generally planar lock adapted to be disposed between said surface and said top for captivating the legs and compressing them together, the lock comprising internal slots of predetermined dimensions through which the legs extend and in which said leg midsections are compressively captivated as the lock is pressed down; wherein each leg midsection of nonuniform width is formed between an outer wedging region comprising a ramp and an inner complimentary edge of each leg, the legs adapted to be aligned in assembly in mutually abutting relation with their complimentary edges compressively facing one another and with their ramps engaging opposite ends of the lock slots in which the legs are captivated, and wherein said leg midsections are compressed together in abutment when said lock is installed; wherein said lower feet diverge downwardly and outwardly away from said leg midsections a distance substantially greater than said predetermined slot dimensions and said upper arms diverge upwardly and outwardly away from said midsections a distance substantially greater than said predetermined slot dimensions, such that the dimensions of the assembled legs in vertical plan exceed the predetermined dimensions of said lock slots; wherein the arms comprise means for grasping the top, and said last mentioned means are drawn into engagement with said top in response to compression of said ramps within the slots of said lock; and wherein the leg midsections comprise ledges for seating the lock.
  • 4. The furniture item as defined in claim 3 wherein the arms comprise ledges for seating the top.
  • 5. The furniture item as defined in claim 4 wherein the top is polygonal, comprising a predetermined number of edges, and the number of legs is equal to said number of top edges divided by an integer number.
  • 6. The furniture item as defined in claim 5 wherein the arms have hooks for grasping the top, and said hooks are drawn into engagement with said top in response to said lock.
  • 7. A modular, knockdown table item adapted to be disposed upon a generally flat or horizontal supporting surface, the table comprising:a generally planar top adapted to be supported vertically above said surface; a plurality of generally C-shaped, planar, radially spaced apart legs for supporting the table, each leg comprising a lower foot for contacting said supporting surface, an integral upper arm for grasping said top, and an integral intermediate region of nonuniform width between said foot and said top and comprising outer edges, and wherein each intermediate region comprises a wedging ramp; a generally planar lock adapted to be disposed between said surface and said top for captivating the legs and compressing them together, the lock comprising internal slots of predetermined dimensions through which the legs nonuniform width regions extend and by which said legs are compressively captivated as the lock is pressed down over said ramps, the legs adapted to be aligned in assembly in mutually abutting relation with their complimentary edges compressively facing one another and with their ramps engaging opposite ends of the lock slots in which the legs are captivated; and, wherein said lower feet diverge downwardly and outwardly away from said intermediate regions a distance substantially greater than said predetermined slot dimensions and said upper arms diverge upwardly and outwardly away from said intermediate regions a distance substantially greater than said predetermined slot dimensions, such that the dimensions of the assembled legs in vertical plan exceed the predetermined dimensions of said lock slots so the legs must be rotated by the assembler when fed through the lock slots.
  • 8. The table as defined in claim 7 wherein:the legs comprise lower ledges for seating the lock; and, the arms comprise upper ledges for seating the top.
  • 9. The furniture item as defined in claim 8 wherein the top is polygonal, comprising a predetermined number of edges, and the number of legs is equal to said number of top edges divided by an integer number.
  • 10. The furniture item as defined in claim 8 wherein the arms have hooks for grasping the top, and said hooks are drawn into engagement with said top in response to said lock.
